.To /rZ/ who/7L it may concern:

Be it known that I, CLAUDIUS B. MoULToN, a citizen of the United States, residing at North Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Gom-V bined Shafting-Boxes and Oil-Reservoirs, of which the iollowingis a specification.

My inventio-n relates to an improved means for preventing the dripping and escape of oil at the ends of the shafting-box and from the shaft.

The invention consists in extending the ends ofthe shaftingbox in a conical form, so that the outer reduced ends will be separated from the shaft just Sufciently to clear it-say one-Sixteenth of an inch. The inner surface ofthe lower extended portion inclines from the outer end to the main portion, and at the lower end of the inclined portion is an opening, which communicates with the oil-reservoir at the bottom of the box, and of which it forms a part, so that any used oil escaping. from the box or from the shaft.will be conducted to the reservoir without any waste or dripping. The .corresponding conicallyshaped extension of the ends ofthe upper portion of the box forms covers, for the purpose of preventing any dirt, dust, brous, or other matter from falling into the lower extension or basin and working into theoil-reservoir.

Referring to the accompanying drawings, Figure l is an elevation or side view of a shafting-box and oil-reservoir embodying my invention. 2 is a vertical horizontal section of the same. Fig. 3 is a plan view of the open lower portion of the box. A A represent portions of shafting sup-` ported in a box, which is divided in the usual manner, to form an upper and lower portion, C B. Each end of the upper and lower portions of the box is formed with a conically? Vshaped projection, c b, converging toward the shaft, the contracted ends being only ashort distance from the shaftsay one-Sixteenth of an inch. The inner lower portion, b, 'of the` extension inclines from the outer edge inwardly, forming a sort of basin, and serves to catch the used oil dropping from the shaft. The ends of the main body of the box J J are curved inwardly, and converge together, as

shown invFig. 3. At the point of convergence (No model.)

is an opening or passage, d, which communicatcs with the oil-reservoir Das shown in Fig. 2, by means of which any oil dropping from the box or shaft is directed to the open.

ing d into the reservoir D.

A band of rubber or other material may be placed around the shaft within the extensions c b, to prevent any oil from extending out on the shaft.

Connected with the lower portion, B, of the box, and of which it forms a part, is an oil receptacle or reservoir, D, having an opening in the bottom, in which is fitted a screw-plug', H. A washer, h, is placed between a shoulder on the screw-plug and the bottom of the opening, to render itoil-tight. By removing the screw-plug, the reservoir D may be cleared of all extraneous matter that may settle at the bottom. At the side of the lower portion, B, is 'an opening leading to the oil-reservoir, over which opening is a half-cup-shaped receptacle, E, into which the oil is poured, and the top of which is so arranged in relation to the oil-reservoir as to indicate when the latter is filled.

F F are hollow projections on each side of the lower portion, B, by which the box is held on hangers or other suitable supports. In the bottom of the lower portion, B, is an opening, in which is tted a conically-shaped holder, I, which is open at the top and bottom, and perforated atits sides, and extends to the bottom of the v'oil-reservoir D. It is heldin the opening'at the bottom of the portion Bby a rim or projection, K, on the upper end. In this holder is placed the wick, consisting of` cotton waste or otherbrous material, by which the oil is fed up to the shaft, the upper end of the wick being in contact with the shaft, so that as the latter rotates, the oil will be carried to every part of its bearing with the box. rlhe inner surface of the box is provided with a lining of Babbitt metal, L inthe usual manner. The two portions of the box are secured together by bolts and the lips G.

The lower portion, B, of the box, together with the oil-reservoir D, the projection E, the projections F F, lips G G, and extensions b c, are all cast in one piece.
